The product line began with Grower's Secret Professional, a fertilizer and plant growth enhancer designed for indoor and outdoor gardening. This highly concentrated formula is made from edible materials, including recycled pineapple waste from the Maui Land & Pineapple canning factories in Maui, pureed papaya, molasses, mushroom spores and other fruit juices, all of which have been fermented.

Grower's Secret Pro is the plant growth enhancer included in Grower's Secret 5-2-1, an all-purpose fertilizer. The 5-2-1 denotes the amount of nitrogen, phosphorus and potassium in the product. Fish emulsion and natural lavender were added to the original product. The lavender masks the smell of the fish emulsion.

These products contain no pesticides or petrochemicals, are safe for pets, people and the environment, and are a rich source of nitrogen, phosphorous, potassium, trace minerals, macronutrients and micronutrients. And, unlike traditional fertilizers, they don't pose a risk of chemical runoff that can contaminate groundwater or aquifers.

I tested the 5-2-1 liquid fertilizer on my lawn. The hose-end sprayer attachment made spraying the lawn a breeze. And amazingly, a few hours later, my lawn looked greener.

Gardeners will find it useful in other ways too, said Chaz Berman, Grower's Secret's CEO.

It will increase crop biomass by around 30 percent, he said, along with creating more uniformity in fruits and vegetables. As an organic home gardener, I'm well aware this is rare in organic gardening.

Another plus of 5-2-1 is that it can reduce the growing cycle by about 20 percent.

"You can get more 'turns,' " Berman said.

The company now offers 11 products for soil and soil-less growing.

"Start" is for the propagation phase. "Green-up" is a super-rich liquid nitrogen product — made from non-GMO soy. It's organic and binds with microbes in soil so it doesn't run off in water, and it's readily available to plant roots.

When combined with Grower's Secret Pro, it works like a plant steroid, Berman said, helping to speed up plant growth.

The company's "Bloom" product is designed for the end of the growth stage, when the company suggests you stop using the fish emulsion product. It's a little higher in the nutrients necessary for blooming, Berman said.

Its "Accelerate" product, a combination of fertilizer and Grower's Secret Pro, is meant for areas in your garden where you have trouble getting things to grow. It contains more phosphate and potassium, which helps plants to grow faster.

The company also has seven products focused on soil and soil-less gardening for hyrdoponics.

Grower's Secret is positioning itself as "an organic alternative."

All of its products are safe easy to use, and include packaging created with recycled plastic, including caps and sprayers.

The products are also safe around pets.

As a recently designated B corporation, Grower's Secret now has a triple bottom line, a measure often known as people, planet and profit. It strives to be sustainable and eco-friendly, including with waste management, facilities and water usage. The company also sends volunteers to urban gardens around the San Francisco Bay area, donating its products to the gardens while putting labor into them. The resulting food goes to help feed the needy.

"We are attempting to lead by example and to make a difference," Berman said.

Grower's Secret is expanding is distribution across the nation. If you have questions, call 888-217-9426. For product questions, contact Sales@growerssecret.com. You can find a retailer or order product at www.growerssecret.com.

Want another way to make a difference this Earth Day besides gardening? Why not become involved with Plant with Purpose.

Plant with Purpose helps alleviate poverty in the world by planting trees and helping poor rural farmers.

As part of the 58: Global Impact Tour (see http://my.live58.org/tour), Plant With Purpose hopes to raise $40,000 to plant 90,000 trees in the Dominican Republic to "restore the fruitfulness of the land and provide food for those in need." Every contribution made during April will be doubled because of a matching grant. It's a simple yet easy way to make a difference this Earth Day. Help plant a tree and transform the life of a farmer.
